I'm a woman with a pregnancy fetish
Oh... You, the man out there who had a fetish for pregnant women, with whom I was open to all sorts of play... You and I experimented with positions good for a pregnant woman while I played one, extending my belly as much as I could, looking at best 4 or 5 months pregnant. For a simple one, you'd lay back, and I would ride your cock, while stretching out my 'pregnant' belly for you to stroke as I rocked back and forth on your cock, coming to find my own pleasure in playing pregnant.
And the one time when we snuck off to a restroom far from activity in the rest of the building, locked the door, took off all of our clothes, and taking a pose easiest, with me facing the mirror above the sink with one of my breasts in one of your hands and my 'pregnant' belly in your other as you took me from behind and came deeply into me. Yes, into me, as that was one of the times we hadn't even comsidered using protection, because a pregnant woman can't get pregnant again.
